<p>This script for QGIS version 2 replaces the default statusbar coordinate display with a configurable widget. Save the script as .qgis2/python/startup.py. Click the statusbar widget left of the coordinates, initially labelled 'EPSG:4326', to select the demanded CRS. Delete startup.py to deinstall.</p>

Revision 2.
</p>
<p>A simple script written as an experiment in geocoding addresses in a database. A list of addresses in the form of "100 Any Street, Anytown, CA, 10010" is passed to a Google Maps URL, and the latitude/longitude coordinates are extracted from the returned XML.</p>
<p>XML methods are not used in this script, but simple string searches instead.</p>

(<a href="/recipes/tags/area/">area</a>, <a href="/recipes/tags/coordinates/">coordinates</a>, <a href="/recipes/tags/triangles/">triangles</a>).
</p>
<p>Plug in three coordinates to triArea(a,b,c), and it will return the area of the triangle.
some common variable letters transfer into these meanings:
m: slope
y,c: y intercept
a: x's coefficient
b: y's coefficient </p>
